Application filed January 22, 1906. Serial No. 297.337.

To all whom it may concern:

Be it known that we, J osnrn R. HOLLAND and CHARLES H. BUCK, of Binghamton, in the county of Broome, in the State of New York, have invented new and useful Improvements in Horseshoes, of which thefollowing, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in horseshoes having removable calks, and refers more particularly to the means for fastening the calks in place and permitting them to be removed when impaired and replaced by new ones without removing the shoe from the hoof.

Our object is to provide the shoe with suitable sockets for receiving and retaining removable calks which are held in place by removable keys, so that by removing the keys the calks may be readily detached and reptalced by new ones when necessary or desira e.

It is obvious that many different forms of keys may be used to lock the removable calks in place, and our present invention contemplates all substantial equivalents of the particular devices shown.

In the drawings, Figure 1 is an inverted plan of a horseshoe equipped with removable calks and our improved fastening means for holding them in place. Figs. 2, 3, and 4 are sectional views taken, respectively, on lines 2 2, 3 3, and 4 4, Fig. 1. Figs. 5 and 6 are modified forms of locking means for the toecalks. Figs. 7 and 8 are sectional views taken, respectively, on lines 7 7, Fig. 5, and 8 8, Fig. 6. Fig. 9 is an inverted plan of a modified form for fastening the heel-calk.

In Figs. 1 to 4, inclusive, of the drawings we have shown a horseshoe l as provided with a toe-calk 2 and heel-calks 3 and 4, said calks consisting in this instance of the comparatively short steel bars tapering transversely, forming V-shaped treads, which are removably secured to the shoe by suitable fastening devices, presently described. The toe-calk 2 is provided with a central threaded shank 5, which is screwed into a threaded aperture 6 in the toe of the shoe 1, the V- shaped edge of the calk running transversely of the toe of the shoe in the usual manner. Just at the rear of the aperture 6 in the toe of the shoe is a second threaded aperture 7 l for receiving a threaded stud 8, having an angular head 9 and a reduced angular portion 10, as best seen in Figs. 1 and 3, the head 9 and angular portion 10 being disposed in a plane below the lower face of the shoe 1 and separated some distance from the rear face of the calk 2. spring or bendable metal, is inserted between the angular reduced portion 10 and adjacent face of the calk 2, with its opposite arms, as 11, engaging opposite sides of the angular portion 10 to prevent loosening or unscrewing of the stud 8, While the head of the key 11 abuts against the adjacent edge of the calk 2, thereby firmly locking the calk, as well as the stud 8, against turning or undue loosening, it being understood that the head of the key 11, which unites the opposite arms 11 together at one end, is substantially equal to the distance between the angular portion 10 of the stud 8 and adjacent rear face of the calk 2. When it is desired to remove the calk 2, the head of the key 11 may be driven or pried downwardly by a suitable chisel or equivalent prying-tool until withdrawn from between the head 9 and adjacent face of the calks, whereupon it may be removed by driving it endwise and downwardly, or the opposite arms 11 may be sprung apart sufliciently to allow the stud 8 to be unscrewed from the shoe sufficient to allow the key 11 to be taken out easily, whereupon the calk may be removed by a suitable wrench or other device capable of unscrewing it from the socket 6. In like manner the calk 3 is provided with a threaded shank 12, which is screwed into a threaded aperture 13 in the heel of one side of the shoe 1 and is held in place against rotary movement by a suitable key 14 and threaded stud 15, the latter bein screwed into a threaded aperture 16, direct y in front of the threaded aperture 13. This stud 15 is provided with an enlarged head 17, abutsocket 13. This key 14 is driven from the out- The bifurcated key 11, of

ting against the lower face of the shoe 1, and

side inwardly transversely of the side of the shoe to which the calk 3 is attached, so as to snugly wedge between the head 17 and calk 3, and-its inner end, which is the smallest, is usually bent upward against the inner edge of this side of the shoe to hold the key in operative position against endwise displacement, and it is clearly evident that when the key is thus secured in place it not only holds the calk against turning in the socket 13, but also looks the stud 15 against rotary movement in its socket 16. When it is desired to remove the calk, it is simply necessary to straighten the upturned end of the key 14 and then drive it endwise and outwardly from between the head 17 and calk 3, where upon the stud 15 may be readily unscrewed by a suitable wrench and the calk 3 may also be removed in a similar manner. The opposite heel-calk 4 is also provided with a threaded shank 19, which is screwed into a threaded socket 20 in the shoe 1, said calk 4 being held in place against rotary movement by a suitable key 21 and threaded stud 22. This stud 22 is screwed in a suitable aperture 23 in the shoe 1, directly in front of the calk 4, but spaced apart some distance from the front edge of said calk to receive the key 21. The head of the threaded stud 22 projects below the lower face of the shoe 1 and is provided with an angular reduced portion 24, forming with the head a recess receiving one edge of the key 21. This key 21 also consists of a tapering piece of metal, as a horseshoe-nail, which is of substantially the same width as the distance and is driven between the reduced portion 24 and adjacent end of the calk 4 to not only lock the calk against turning or rotary movement in the socket 20, but also locking the shank 22 against rotary movement in its socket 23, the inner or smaller end of the key 21 being bent or turned upwardly against the inner edge of the shoe to hold it against'endwise displacement.

In Fig. 5 we have shown a horseshoe-calk 2, similar to that seen in Fig. 1 and 3 and provided with a threaded shank 5, which is screwed in a socket 6 in the shoe 1, said calk 2 being held in place by a key 11 and opposite retaining members 9'," one at each end of the calk. These retaining members 9 are provided with threaded shanks 8, each of which is screwed into a threaded socket 7 in the shoe 1, the lower ends of the retainers 9 being provided with recesses 10 for receiving the key 11, which fits snugly in the recess 10 and abuts against the adjacent face of the calk 2. The key 11 lies flatwise against the rear face of the calk 2 and has its opposite ends passed through the recesses 10 and bent laterally against the outer sides of the retainers 9 to lock said retainers against rocking movement and also serving to lock the key 11 against endwise movement,

thereby firmly locking the calk 2 against turning in the socket 6. The retaining members 9 are each extended beyond the adjacent rear edge of the calk 2 and abuts against the end faces of said calks to limit their inward rocking movement and at the same time additionally support the calk against'turning movement inits socket 6. When it is desired to remove the calk 2, it is simply necessary to straighten the ends of the key 11 and drive it endwise out of the recess 10, whereupon the retainers 9 may be turned outwardly bya suitable wrench, and the calk may be unscrewed and removed by the same wrench.

In Fig. 6 we have shown a shoe 30 as provided with a tapering socket 31, in which is inserted a toe-calk 32, having a fiat tapering base-plate 33 wedging in the tapering socket 30, said base-plate being formed with a lengthwise opening 34, which in this instance terminates in an enlarged opening 35 for receiving a T-bolt 36. The T-slot 34 extends entirely through the base-plate 33 of the calk 32, and the bolt 36 is loosely fitted in and is adapted to be removed from the slot 34, and its inner end is threaded and projects beyond the inner face of the toe of the shoe 30 and is engaged by a nut 37 and yielding washer 38, the latter being clamped between the nut and adjacent inner edge of the shoe to prevent in a measure loosening of the nut 37. The tapering base-plate 33 of the calk 32 fits closely in the tapering socket 30 and tapers inwardly from its outer edge, so that when the nut 37 is tightened against the inner edge of the shoe the calk 32 is wedged inwardly into the tapering socket 30 and rigidly held in place. When it is desired to remove the calk 32, it is simply necessary to remove the nut 37 and -washer 38, whereupon the calk may be drawn outwardly from the socket 30 and the bolt 36 removed therefrom and replaced in a new calk,- which may be reinserted into the socket 30 and clamped in place in the manner described. This bolt 36 serves as a removable key-locking member to hold the calk 32 in place and is believed to be the substantial equivalent and within the scope of the invention involved in the clamping devices seen in Figs. 1 to 4, inclusive.

In Fig. 9 we have shown a portion of the heel of one side of the shoe as provided with a heel-calk 40, having a screw-threaded shank 41, which is screwed into a threaded socket in the shoe and is held against turning by a plate or washer 42. This plate has one end abutting against the adjacent face of the calk to prevent turning of the latter and is provided with an elongated slot 43, one end of which is enlarged for receiving a screw 44, which is screwed into a threaded aperture 45 in the shoe in front of the calk 40 for the purpose of holding the calk flatwise against the under surface of the shoe and preventing its backing away from the calk by reason of the fact that the front side of the slot is smaller than that through which the head of the screw passes. The rear end of the slot is of substantially the same width or slightly greater than the diameter of the shank of the screw, so that by unscrewing the latter a slight distance the plate may be moved forwardly a suflicient distance to allow the calk to be unscrewed and removed when worn and replaced by a new calk.

What we claim is 1. In combination with a horseshoe having a threaded socket, acalk having a threaded shank screwed into the socket, a stud at one side of the calk and a key inserted between the calk and stud to prevent turning of the calk in the socket;

2. In combination with a horseshoe having a calk-receiving socket, a calk detachably seated in the socket, a rotary stud seated in the shoe at one side of the calk and a key fitted between the calk and stud to lock both against rotation.

3. In combination with a horseshoe having separate threaded openings, a calk having a threaded shank screwed into one of the openings, a stud having a threaded shank screwed into the other opening and a key fitted between the stud and calk to prevent turning of the latter.

4. In combination with a horseshoe having apertures arranged in pairs, a calk and a stud each rotatably seated in one of the apertures of each pair, and a tapering key wedged between each calk and its associate stud for locking them against rotation.

In witness whereof we have hereunto set our hands this 11th day of January, 1906.
